Now that both the Samsung Galaxy S6 and HTC One M9 are available, comes the big question for Android fans: Which phone should you buy? I've got specs and advice.
Both phones are beautifully designed. The S6 got the more significant makeover, forgoing the plastic of the previous version and moving to aluminum and gorilla glass. The One M9 looks more like its predecessor, but then again, it's predecessor was a better designed phone than the S5. The S6 is slightly smaller and slightly lighter, at 4.87 ounces compared to the M9's 5.54 ounces. Based on that, and on a more refined design, I'd give the slight edge to the Galaxy S6.
The S6 wins in this category. It's got the best screen on a smartphone today. The screen is only slightly larger than the M9, at 5.1 inch compared to 5 inches, so that's a tie. But resolution tells the tale: 1440 x 2560 pixels and 577 ppi versus the 1080 x 1920 pixels and 441 ppi for the M9.
Processor and RAM
Both phones ship with 3 GB of RAM, and both have 8-core processors, the HTC with the Qualcomm Snapdragon 810, and the Samsung with the Samsun Exynos. Some reviewers have said that the Samsung feels slightly faster. But it's really too close to call, so this is a tossup.
You can get up to 128 GB of storage on the Samsung Galaxy S6, but only if you're willing to open your pocket wide. The M9 comes with just 32 GB of built-in storage, but there's a microSD slot that can handle up to 128 GB of additional storage. That makes the M9 more flexible, so it gets the nod.
On paper, the M9 should win, because of its superior specs: 20 megapixels versus 16 megapixels back-facing camera, although the S6's front-facing camera is 5 megapixels versus the M9's 4 megapixels. But the built-in software and image stabilization on the S6 is superior. So I'll give the advantage to the S6, although this is a close one.
The S6 has a fingerprint scanner for security. The M9 doesn't. The S6 gets the nod.
Both are great phones, but the S6 gets the slight edge. It's slightly lighter and smaller and more nicely designed, its photos are superior, its screen better, and it's got a fingerprint scanner. The M9's storage options are more flexible, but that's not enough to make up for everything else.
